When running the 64bit version of Rage GPU transcoding seems to have no effect. It says it's enabled in the menu, and the vt_useCudaTranscode CVar updates properly, but it makes no difference to the benchmark scores and in-game I'm getting crazy high CPU usage which results in a lot of stuttering for things like explosions and enemy spawns. Even forcing the vt_useCudaTranscode option to 2 doesn't help.

I don't have the same problem on the 32-bit version. I'm using the latest nVidia beta drivers (314.21) on a 560ti and 2500k CPU

Does anyone know if there's a fix for this? Or if we might see mod support for the 32bit version in a future update?
